Photovoltaic Systems

After the successful participation in the course Photovoltaic Systems the students are able to:

select optimal (standalone, decentralized) PV systems according to specific application and resources conditions
estimate the techno-economic performance criteria implement standard PV simulation software tools for system design.

Decentralized and stand-alone PV hybrid systems:
- modular PV systems technology for decentralized AC-power supply
- large decentralized PV systems (fixed mounted and tracking systems, power condition units and grid integration)
- PV stand-alone and hybrid systems configurations and components performance;
- supervisory control and energy management strategies for PV decentralized systems;
- storage technology for PV stand-alone systems (super-capacitors, batteries, electrolysis and fuel cells);
- power conditioning units for decentralized and stand-alone PV-Systems and components (battery charger, bidirectional converters, fuel cell inverters);
Economics:
- specific energy cost calculation
- techno-economic performance criteria of stand-alone PV and hybrid systems
Design aspects:
- methodologies for sizing PV hybrid systems
- design of stand-alone PV hybrid system (load demand synthesis, component sizing, evaluation of performance criteria)
- implementing simulation tools for designing PV stand-alone systems case study via project work (design of stand-alone PV system).

After the successful participation in the course Energy Efficiency in Buildings the students are able to:

understand physical and technical aspects of energy flows in buildings
identify heat gains, heat losses and cooling demand of rooms
determine life cycle costs and life cycle assessment of environmental impacts in the building sector

Basics of building physics:
- heat transfer adapted to building elements like walls and windows
- shading devices, humidity and condensation effects
- global radiation on building
Conventional vs. unconventional energy use in buildings:
- thermal comfort, ventilation
- boilers, cogeneration of heat and electricity, heat pumps
- passive houses
Economic aspects of EE in the building sector:
- costs and savings of energy efficiency measures
- life cycle costs and life cycle assessment of environmental impacts
